Summary

John McLean Meegan v. Boyle — Opinion of the Court

But whether it be a genuine instrument or not, it has not been treated as valid, as no claim has been set up under it, and all the heirs have acted, in regard to the estate of their father, as though he had died intestate.
Neither the deed to Chouteau, nor the will, can be admitted in evidence, without proof, as an ancient instrument. The rule embraces no instrument which is not valid upon its face, and which does not contain every essential requirement of the law under which it was made.

John McLean Meegan v. Boyle — Opinion of the Court

And if the cause of action accrued at the termination of the life estate of the husbands, then, by all the statutes ever in force in Missouri, twenty years at least would be given wherein to sue.
